(CNBC) Pfizer CEO Albert Bourla said Thursday people will “likely” need a booster dose of a Covid-19 vaccine within 12 months of getting fully vaccinated.
He also said it’s possible people will need to get vaccinated against the virus annually.
“It is extremely important to suppress the pool of people that can be susceptible to the virus,” he told CNBC’s Bertha Coombs during an event with CVS Health. He added the vaccines will be an important tool in the fight against highly contagious variants.
